tmux-powerline is a shell-based status generator and plugin for the tmux terminal multiplexer. It provides a visually segmented status line that displays real-time system metrics, session information, and version control status.
The project allows for high extensibility through a modular segment architecture, enabling users to define custom information blocks via shell scripts. Visual arrangements and color schemes are managed through external theme files and environment variables.
The system monitors a broad range of hardware and network metrics, including CPU load, memory usage, battery levels, and IP addresses. It also integrates version control tracking to display current branches and repository states, alongside reporting on background application states and external service data.
